yes, the KN-163 is the correct filter for all oilheads, R1100 & R1150.
teh advantage of the K&Ns is that a special filter wrench is not needed for installation/removal- just a metric socket (they have a nut welded onto the bottom face of the filter).
Mann's are fine, as are Bosch. K&Ns also have tested very well.

Been using the Bosch 72161 filter, which I believe is the same as the Bosch 3330. You can get the 72161 from Beemer Boneyard and it is available from others too. This would be in my 2001 R1100RT, 99k miles.

If you read this article, Oil Filter Review and Tests, and believe it, you'd steer away from Fram and select Mobil1, Purolator or Bosch.

Unfortunately, none of the filtration tests or claims are performed by third party lab testing. I rarely believe what a manufacturer states unless they have an extremely good reputation that is maintained over time.

The following pics clearly show differences in filter construction. Both oil filters are for the same vehicle. The top is a Fram oil filter. Note the cardboard end caps. The bottom is a Mahle oil filter.

I don't cheap out on oil filters. I'm amazed that forum members will discuss "which oil" ad nauseam and then discuss how to save a buck on an oil filter.

I have to ask, why is a anti drainback bladder required? I call it a valve.

The filter stays full because of its position.

I asked because the OC91 may be a Mahle equivalent, but the BMW may be custom made for BMW without the anti-drainback bladder. The pic of the open BMW filter above does not show one and neither does it need one being mounted upside down. I pre-fill them when installing a new filter.
